The function f(t) = 25 sin (pi over 2t) + 10 models the temperature of a periodic chemical reaction where t represents time in hours. What are the maximum and minimum temperatures of the reaction, and how long does the entire cycle take? (5 points) A. Maximum: 25°; minimum: 10°; period: pi over 2 hours B. Maximum: 35°; minimum: 35°; period: 8 hours C. Maximum: 100°; minimum: −15°; period: pi over 2 hours D. Maximum: 35°; minimum: −15°; period: 4 hours
Accepted Solution
A:
f(t) = 25 sin [(π/2) t] + 10
By graphing the given function The correct option is D D. Maximum: 35°; minimum: −15°; period: 4 hours
